Build in redundancy and layers (no single point of failure)
Exactly!
That's why, for example (a comprehensive list would be much longer):
1) I looked high and low to finally find and buy a small Class C RV that ... from a raw weight viewpoint ... required only the Ford E350 chassis but was optionally built on the Ford E450 chassis. This overkill action was to "just in case" have - very large brakes, very large transmission cooling capacity, and a very stable wide(r) rear dually stance - to in the long run provide "less things to let us down".
2) I carry along complete tire changing capability, even though I hope to never have to change a flat inside rear dual when offroad out in the middle of nowhere with the RV.
3) I carry along five ways to keep the coach battery bank charged up - the large built-in generator with two different chargers, a small portable generator with the same two different chargers, and the engine alternator. ( We may have six ways soon - by adding a portable solar panel that can be set up/out to be in the sun even when the RV is camped in the shade.)
4) I carry along long range cellular tower access capability so we can make emergency calls or surf the Internet when out in the middle of nowhere with the RV.
5) I carry along three ways of heating the RV and two ways of cooling the RV.
6) I have a built-in roof access ladder so as to always be able to get up there anyplace, anytime.
7) I carry along a spare serpentine engine belt and a spare coach water pump.
8) I carry along spare igniters for the RV refrigerator and the RV water heater.
9) I sometimes carry along a portable refrigerator just in case the main coach refrigerator should fail out in the middle of nowhere.
10) I carry along two complete sewer drain hoses.
11) I use AGM coach batteries so that no "messing around with battery maintenace" is required.

Focus more on avoiding things that don’t work than trying to find out what does work
Exactly!
That's why my entire 37 year professional career was spent as a Test Engineer - where one checks for things that work wrong ahead of time, so that other folks would end up with things that work right.
It all boils down to a footnote another poster uses: "If you're not paranoid ... then you're not paying attention." Recent (Western World) generations have no concept of being prepared for the unexpected or how to deal with things that don't go as assumed. What ever happened to the good old fashioned Boyscout/Girlscout mentaility?
By the way, I gotta read up on who this "Magnus" character is, or was. :h
